These goggles fulfil my needs. The Awua Sphere Keyenne goggles fit well, are durable, low profile, and handle the rigors of triathlon racing and training. Fit is a very personal situation and these fit my head well. I like the quick adjust buckles on the straps that help one fine tune the fit and pressure on the face. I have had the pair of Keyenne goggles that these were suppose to replace for about 2 years and use them 1-3 times per week. They are low profile but have a good field of view so one can easily sight during open water swims yet not do large that they are easily disrupted or kicked off during a race. I though my old pair was leaking and that is why I bought this pair but found out what it wa hair around the seal that caused the leak so now I have a backup pair in case I lose the old pair or can't find it at a race. Overall these are good, durable, comfortable, and well make goggles and I've been pleased with their function for several years.
